Title: Light amplifier
Inventor: MIMURA HIDENORI
IPC: H01S3/06
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a high output. SOLUTION: A light amplifier fiber 10 has a double clad construction comprising a first clad and a second clad which are excited by a core 10a to which a first element emitting with a wavelength λs of signal light and exciting light (wavelength λp) and a first element which generates the exciting light (wavelength λb) generating the second element are added. The signal light propagates through the light fiber 12 and is incident to a wave adder 14. Exciting light (wavelength λp) output from the exciting light source 16 is incident to the wave adder 14 through a converging lens 18, multilayer film reflecting mirror 20 and light fiber 22 having a large core diameter. The multilayer film reflecting mirror 20 transmits wavelength λp but reflects wavelength λb. The wave adder 14 makes a signal light from the light fiber 12 incident to the core 10a and makes the exciting light from the fiber 22 incident to the first clad 10b. A multilayer film mirror 32 at the opposite end of the light amplifying fiber 10 transmits the signal light and reflects light generated from the second element.

Title: Error control preventing system for remote control system
Inventor: HAYASHI MIZUYASU
IPC: H04L1/08
Filed: 1990-02-07
Abstract: PURPOSE:To prevent the malfunction of an equipment caused by the quality change of data, etc., without fail by transmitting the control command of the same contents from a master station device to a slave station device plural times for executing the control command to the specified control object equipment, respectively holding the plural received control commands by the slave station devices, executing comparison and collation, and executing the contents of the control command only when the result is satisfactory. CONSTITUTION:Based on information stored in a ROM 22, on the side of a slave station 2, it is investigated whether the received control command data requires error control prevention or not. When the error control prevention processing is required and the three pairs of control command data A, B and C, which are continuously transmitted, are received, these data are stored in respectively separate registers 61, 62 and 63. Afterwards, the information of all registers 61-63 are compared, collated and checked by an AND circuit 64. Only when all the information in all the registers 61-63 are coincident, the contents of the control command are correct. Namely, the objective equipment is controlled while judging the quality change of data is not generated.

Title: Wireless arithmetic and logic unit
Inventor: KANBARA SHIRO
IPC: H01L29/423
Filed: 1994-02-25
Abstract: PURPOSE:To reduce a wiring capacity to be a stray capacity to a tunnel joining capacity by arranging plural conductive materials connected by a single electron tunnel phenomenon at a prescribed position. CONSTITUTION:A logic circuit 101 divides the surface of the two-dimensional plane of a substrate executing element arrangement into plural equilateral hexagons 102 and arranges the conductive materials 105 at the vertexes 110 of the respective equilateral hexagons 102 so that the vertexes 110 and the center of a circle of the bottom of the conductive materials 105 in the shape of a cylinder are coincident. When two conductive materials 105 are arranged on the same side 111 on one equilateral hexagon 102, the two adjacent conductive materials 105 are combined by the single electron tunnel phenomenon by way of a fine interval and in another case, the combination between the conductive materials 105 by the tunnel phenomenon is not generated. The existence of combination by the single electron tunnel enables a signal, namely one electron, to be propagated between the conductive materials 105 without wiring. This reduces the wiring capacity to be the stray capacity to the tunnel joining capacity.

Title: Manufacture of semiconductor surface protection film by decomposition of phosphazene and phosphazan compounds
Inventor: FURUKAWA YOSHITAKA
IPC: H01L21/318
Filed: 1987-02-09
Abstract: PURPOSE:To enable a high-quality protection film to be formed easily on the surface of a compound semiconductor, by utilizing the fact that a substituted or partially substituted product obtained from (NPCl2)n(n>3) is decomposed easily at a temperature of 300 deg.C or below and forms a P-N or PON film on the semiconductor surface. CONSTITUTION:Phosphorus nitride dichloride (NPCl2)n(n>3) is reacted with a nucleophilic reagent such as alkoxide, phenoxide or an amino compound to synthesize (NP)nC2n-xRx. This compound is decomposed at a temperature of 300 deg.C or below, whereby a P-N or PON film can be formed on the surface of a semiconductor. The P-N or PON film thus formed on the surface of the semiconductor does not contain P-C bond having strong ionic bonding property which would be hydrolyzed easily and, therefore, the lifetime of such film is not decreased by moisture. Further, if a partially substituted product in which chlorine is left unsubstituted is utilized, the decomposition of the compound accompanies production of hydrogen chloride. The hydrogen chloride thus by produced serves as an etching agent for etching the surface of the semiconductor and it is advantageous for the production of a protection film.

Title: Preventing edge overcoat in continuous galvanizing
Inventor: ETOU KENZOU
IPC: C23C2/20
Filed: 1978-03-13
Abstract: PURPOSE:In continuous galvanizing line, immediately after steel plate is passed through plating rolls, inert gas is jetted through wide-opened, elongated nozzle onto the both sides of the plated steel, thereby preventing the generation of edge overcoat, and enhancing the quality of the plated steel. CONSTITUTION:Steel plate 5 is passed through the pair of rolls 3 dipped into molten zinc 4, the both side of galvanized plate 5 is immediately jetted with inert gas such as N2 at both edge sides. The edge nozzles 6 having wide-opened elongated opening 7 are directed at the center of the plating rolls 3, jetting the gas at a pressure of 1500 to 2500 mm H2O which is 2 to 3 times greater than the usual value. As a result, molten zinc pool between the roll 3 and the plate 5 is blown toward inside, rendering plating layer uniformly distributed, thereby to eliminate the overcoat at the edge portions. The process thus enhance the quality of the products and reduces production cost as well as the consumption of corrugated board to be used for preventing build up when winding the steel plate.
